This'invention relates to yimprovementsin advertising and similardisplay apparatus. The presentapplication is a substitute for anapplication filed by Ime June 7, 1922,

Serial No. 566,576. 'Y

The Value of any sign or display device depends primarily on its abilityto attract and hold the attention of the observer and in this connectionthere are three factors 1o which are of prime importance, namely, theeffects of motion, color, and mystification. lEach of these factors hasits own value when present in a sign or display device or apparatus andwhere twoor more of thefactors are present Lthe ability of the sign toattract and hold attention is greatly `en hanced. Usually, however,signs or other display devices or apparatuses which vembody two or allthree of the factors enumerated are expensive to install and maintain inoperation. l Therefore, it is the primary object of the presentinvention to provide a sign or display apparatus in the operation of'which the effects of motion,

color, and mystification will all be present and in which sign or thelike the structure will beso simple as to adapt it for generaladvertising and display purposes.

More specifically, the invention has as 3 its object to provide a signin the operation of which there will be presented to the ob-v serverlthe effect or sensation of an ever changing array of colors, eachcolor'originating at a central point and gradually eX- panding andblending, in a more or less annular form, with colors previouslysimilarly originated, this ei'ect being produced through the rapidrotation of certain component parts of the apparatus and the senduced atthe same time' By an arrangement of the component elements of therotating color devices, there is also produced the effeet of a signdisplay surface or the like being gradually brought to clear view from acondition of indistinctness and then being sation of motionI being inthis manner promay be automatically successively broughtv to viewat'various Vperiods in the operation of the apparatus.'

Another object of the inventionis to provide a sign or display apparatuswhich may be installed in store windows or within interiors and in lareembodments may be used in theoutdoor display of advertising matter.Likewise theinvention contemplates the provision ofI a display apparatuswhich may be employed as an attractive front for carnivals, shows,amusement parks, etc. Also the invention contemplates an apparatus inwhich the various effects produced maybe displayed by projection onto ascreen as, for example, a motion picture screen or a screen stretched ina shop window.

1n another embodiment of the invention, means is provided for displayinga sample or an actual specimen ofthe article advertised, the said sampleorspecimen being in an undisclosed manner brought to full view of theobserver and then retracted and for a time concealed from view. In afurther.

'llhe embodiment of the apparatus illustrated in Figs. 1 to 4 inclusivecomprises a casing indicated in general by the numeral 1 and supportedupon a suitable base 2 or in any other manner found expedient. 'llhiscasing comprises a circumferential or cylindrical wall 3, a back wall 4,and a front 5 having a display opening 6 therein. rll`he apparatusfurther embodies a rotatable display member indicated in general by thenumeral 7 and this member preferably comprises a circular front plate 8having a concentrically located aperture 9, the purpose of which will"presently be explained. A spider 1() is arranged in rear of the faceplate 8 and in spaced relation thereto and at the point of juncture ofits arms is provided with a hub 11 which projects rearwardly from theplane of the spider and rotatably fits a stub shaft 12 which projectsforwardly from the upper portion of a ixedly supported upright 13located within the casing 1.

rllhe numeral 14 indicates an electric or other suitable type of motorfroml which power is to be derived for operating the apparatus and uponthe shaft 15 of this motor there is xed a pulley 16 about which istrained a belt 17, the belt passing alsoI about a pulley 18 either xedupon or constituting aninteg'ral art of the hub 11 of the display member7. In this manner rotary motion is imparted, preferably at a high rateof speed to the said member 7, and the member, while in rotation, may beviewed through the display opening 6, the `face of the plate 8 beingpresented toward this opening. If desired, variously arranged colorareas may be provided upon the face of the said front 8 of the member 7,as, for example, concentrically or eccentrically arranged color areas19, as shown in Fig. 1.

In combination with the display member 7, there is provided a colorimparting medium or display member whichis indicated in general by thenumeral 20 and this medium preferably comprises a flat circular disc.21, the face of which is divided into a number of sector-like areas 22which may be given different colors. For example, the

areas or fields 22 may be colored red, blue, yellow, and green, and oneif desired may be colored white, the disc 2l being provided, preferablyin this' latter eld, with a display opening 23 which isof substantiallythe same diameteras the opening 9 and in certain phases of operation ofthe apparatus to be presently described is adapted to be brought intosubstantiall registrationv with Maasai said opening 9. The disc 21 ismounted axially upon a stub shaft 24 projecting from the forward face ofthe front 8 of the display member 7 and the disc 21 is provided with ahub 25 4having a sprocket gear 26 fixed thereon. A. sprocket chain 27 istrained about the gear 26 and about a similar gear`28 fixed upon theforward end of `a shaft 29 journaled at the periphery of ,the member 7.A worm gear 30 is fixed upon the rear end of the shaft 29, and a worm 31at the outer end of a shaft 32 meshes with the said worm gear. rlheshaft 32 is rotatably journaled in suitable bearings 33'upon one of thearms of the spider 10 and at its inner end hasV ixed upon it a worm gear34 which is in mesh witha worm -35 upon the exterior of a collar 36which is loosely fitted onto the hub 11 of the member 7 in frontvof thepulley 18. rllhe collar 36 is notched-at one point in its circumferencein its rear end, as at 37, and a resilient locking nger or pawl 38 isfixed at one end, as at 39, upon the upper end of the upright 13 and isprovided with a toothed end 40 which engages in the notch 37 and in thismanner serves to hold the collar 36 against rotation with relation tothe hub 11 and at the same time permitting of free rotation of this hubupon the stub shaft 12 and Within the collar. At this point it will beevident that as the member 7 is rapidly rotated through rotation -of itshub 11, the worm gear 34 will be carried around the worm 35 and in itstravel will be given slow rotative movement which is imparted to theshaft 82. In this manner relatively slow'rotative movement is impartedby the worm 31 and worm gear 30 to the shaft 29 and the motion istransmitted from this shaft to the hub of the medium 2O thus rotatingthe disc 21 comprising this medium. As the member 7 rapidly rotates, themember 20 is carried around with the same and the colors of thesector-shaped areas or fields 22 will be caused to blend with oneanother and with such color areas or fields 19 vas may be present uponthe face of the front 8 of the said member 7. rlhe speed vo f rotationlof the member 7 is in practice so rapid that the character of the member20 is not perceptible to the eye and the presence of this member isnoticeable only by reason of the blending of its several color fields.When one of the color fields, as, for example, the red ield, is inposition oppositethe central portion of the face plate 8, the opening 9will, of course, be closed or covered and, in the rapid rotat-ion of theassemblage,1 `a central red area or zone will be presented to view, andsurrounding this area will be presented a number of concentric zones ofvarious colors produced through blending of t-he various color areas orfields 22 and also the areas ing 9.

or fields 19. As the apparatus continues to operate, the disc 21 will beslowly rotated and the next color field 22, in order, will' tion of thedisc 21, the initially relatively y small spot of red at the center ofthe display surface in general will be seen to pand in all directions,and likewise t e blended colo'r zones surrounding thisr ce tral zonewill be seen to expand and eventui ally disappear from v iew. At thevsame time the colors will be continuously blended' in a manner toproduce practically every conceivable color and tints thereof, and ,the

composite color field thus produced will, in fact, be continuouslychanging its aspect,

f resentino' a most leasin a "earance to the eye and holding theattention of the observer. As previously stated, the speed of rotationof the disc 21, is relatively low so that the blending of the colorareas or fields will be more or less graduai and yet the sensationexperienced will be that of extreme rapid motion. Finally in theoperation of the apparatus, the color area in which the opening 2 3 islocated will be brought gradually to position in front of the opening 9.Means is provided in back of the opening 9 and face plate 8 in whichthis opening is' formed, bearing advertising or display areas, and asthe opening 23 gradually eclipses the opening 9, the matter displayed inrear of the opening 9 will be at first 'dimly and indistinctly broughtto view and will then be graduallyn more clearly defined as the opening23 is brought more nearly into registration or alinement with theopening 9. Finally, the openings will be thus positioned and theadvertising or display matter will be exposed clearly to view throughthese openings and the display opening 6. Continued operation of theapparatus will result in the opening 23 again eclipsing the opening 9and in a gradual manner so as to produce the effect of a gradual fadingfrom View of the advertising or display matter previously dis-y playedthrough said openings 9 and 23.

The operation is then automatically repeated in the manner. justdescribed.

The medium employed for displa ing the signs or other displa matter anda j ve referred tois indicate in general by the numerall 41 andv in thisform of the invention preferably Acomprises a circular disc 42 which isrotatably mounted upon a. -stub shaft -43 projecting from a dependingarm 44 secured preferably by `eoacting jamb. or clamping' nuts 45 upon'the forward end of the stub shaft 12, the arm 44 being in this mannerrigidly supported. The discv 42 is located within the bounds of themember 7 and in rear ofthe face plate 8 thereof and itis provided uponits forwardly presented 'face 'with a`number of advertising or displayareas 46 which may be of vdifferent characters and which'are to besuccessively displayed. The fields or` areas 46 are so arranged in anannular series about the center of the disc 42 that when thedisc iesrotated through predetermined angular distances the fields or'areas willbe successively brought to position op- A ,y

posite the opening 9 and will, of course, be presented to view when theopening 23 is.

tions prevlously explained. In order that the disc 42 may be held ineach of the positions to which' vit isA automatically rotated by meansto be resently pointed out, a cross piece 47 is 1 xed transversely ofthesupporting armf44 and an upwardly bowed leaf spring 48-is fixed at oneend, as at 49, upon the upper side of the cross piece and' has its Yother end 50 resting freely in engagement with the upper side of thecross piece. A number of studs 51 are arranged in an annular seriesabout the axis of the disc 42 and project from the rear face of saiddisc and in each position -of rotative adjustment of the disc, two ofthese pins or studs will simultaneously engage the oppositesides of thebow or bulge in the spring 48. When rotative movement is imparted to thedisc 42 to shift it from one position of adjustment to another, one ofthe studs or pins 51 will ride over the bow or bulge of the spring andfinally when the disc comes to rest it, together with the next stud orpin in the series,

will be positioned in engagement with the' spring and the disc will thusbe held in its new position of adjustment. In order to automaticalleffect rotative adjustment of the disc 42 intermittently duringoperation of the apparatus, a tappet finger 52 'is fixed upon theforward end of a shaft 53 rotatably mounted through the bore of thehollow stubv shaft 12,'and upon rotary motion being imparted to this,shaft the tappet finger 52 will at suitable intervals sweep intoengagement with the successive pins 51, thus intermittently rotating thedisc 42. In ordert to impart rotary motion to the shaft 53, a sprocketgear -54 is fixed upon the rear Vend of the shaft, and a sprocket chain55 is trained -about this gearand about a gear 56 fixed uponi'the rearend of a shaft V57 journaled through the upright 13. A worm gear 58 isfixed upon the forward end of the shaft 57 and meshes with a worm 59provided upon the lower end of a shaft 60 journaled in suitable bearings61 vupon the said upright 13.- A worm gear (i2-is fixed upon the upperend of theshaft v60 and meshes with a worm 63.which is keyed upon therear end 'of the hub 11. Thus as the member 7 is rotated,

corresponding motion will be imparted to the opposite the'said opening 9under the condilis front of the casing 1.

worm 68, and a slow rotative movement will be imparted to the shafts 60and 57 and finally to the shaft 53.

ln order that the display surface of the sign may be suitablyilluminated, alight 64e may be provided at the upper side of the Ufcourse, in the daytiinethe displa surface will be sufficientlyilluminated y natural light, and the electric light 64 need, therefore,be only employed at night.

Fig. 5 of the drawings illustrates a simplified embodiment of theinvention in which an upright 65 is iixedly mounted in any suitablemanner and is provided near its upper end with a forwardly projectingfixed shaft 66. Rotatably mounted upon this shaft is the hub 67 of adisplay medium, indicated in general by the numerall 68, andcorresponding to the medium 7. Ilihe medium 68 comprises a face plate 69and a spider l70, as in the previously described structure,

and the face plate is provided centrally with an opening 71corresponding to the opening 9. A shaft 72 is rotatably Journaled in themember 68 and has }"fixed upon its forward I end a color impartingmedium 78 comprising a disc 74 which may be provided with variouscolorfields or areas corresponding lto the areas 22 of the disc 21 previouslydescribed. Like the disc 21 this disc 74 is also provided with anopening 75 which is adapted to be brought opposite or substantially inregistration with the opening 71. A worm `gear 76 is fixed upon the rearend of the shaft 72, and a Worm 77 is provided at y .the outer end of ashaft 78 and meshes with this gear. The shaft 78 is mounted in suitablebearings 79 upon one arm of the spider 70, and a worm gear 80 is fixedupon the inner end of the shaft 78 and meshes with a Worm 81 which isloosely fitted on to the hub 67 and is held stationary in the samemanner as the worm 85. It will now be evident that as rotary motionisimparted to the member 68 at a high rateof speed, corresponding motionat a low rate of speed is imparted to the member 7 3 4and substantiallythe same eHects will be produced as in the previously described form.

Rotary motion is imparted 4to the hub 67 through the medium of a belt 82which is trained about pulleys 83 and. 84 mounted, respectively, uponthe hub 67 and the shaft 85 of an electric or other suitable type -ofmotor 86. In this form of the invention,

vthe display or sign medium is indicated in suddenly presented to theview of the observer and subsequently retracted and then concealed for aperiod of time after which it is again presented to View, and in thisfigure the numeral 89 indicates a standard corresponding to the standardor upright 13 and provided with a forwardly projecting tubular stubshaft 90 upon which is rotatably mounted the hub 91 of the rotatabledisplay member 92 which corresponds to the niember 7 heretoforedescribed. Vlhe hub 91 supports a worm 98 corresponding to the worm 35and operating in the identical manner and serving the same purpose asthe previously described worm. Also there is .fixed upon the hub 91 aworm 94 corresponding in function to the Worm 63 and transmitting motionat a relatively low rate of speed to a sprocket gear 95 corresponding tothe gear 54 and fixed upon a sleeve shaft 96 rotatablyjournaled in thetubular stub shaft 90. rlFhe numeral 97 indicates a bracket arm which isfixed upon the forward end of the stub shaft` 90 and rotatably supportsa sign displaying med-iurnl 98 corresponding to the medium 41 previouslydescribed and comprising a disc 99 bearing a substantially annularseries of sign ordisplay surfaces corresponding to the surfaces 46.However, this series is interrupted at one point by an opening 100formed in the said disc 99, and it will be understood from what has beensaid with regard to the 0peration of the form of the invention shown inFigs. 1 to 4 that at a period in the operationof the apparatus theopening 100 will be brought opposite the opening in the face plate ofthe member 92 and the opening in the color imparting disc which is notshown in this view but correspondsto the disc 20. An arm 101 is fixedupon the forward end of the sleeve shaft 96 and hasa forwardly directedfinger 102 adapted to successively engage pins 103 projecting from therear face of the disc 99 and corresponding to the pins 51. Thus insubstantially all respects this structure, as `so far described, is-substantially identical with the corresponding structure shown in Figs.1 to 4, inclusive. However, in this modified form a supporting rod 104:is slidabl mounted through the sleeve shaft 96 an located as to beopposite the opening 100 when the opening is in the position abovedescribed. rllhis end of the rod 104 supports the sample or specimen ofthe article advertised or some object pertainin as, for example, apowder puff, indicated by the numeral 105, where such an. article or theface powder to be applied thereby is the 'subject of the advertisingmatter. The

rod 104 projects at its rear end beyond the" rear end of the sleeveshaft 96 and is urged in a forward direction, yieldably, by a spring hasits forward end so thereto with an angularly directed linger 107 havinga nose 108 engagingthe working surface yopening 100 and into plain viewof the yobserven t Fig. 7 of the drawingsillu'strates a modilication ofthe display surface in which the advertising matter to be displayed bythe member 4l heretofore described is adapted to be brought suddenlyintoview when the openings 9 and 23 arein position opposite each other.In this structure, the `display medium, corresponding to the medium 7,is. indicated in general by the numeral 111, and the color,impartingmedium, correspondlng to the medium 20,- is indicated in' general bylthe numeral 112. This latter medium, as

in the former instance, comprises a disc 113 provided with a selectedarrangement of color fields or areas and formed at one point with anopening 114 corresponding to the opening .23. Stop pins 115 and' 116 arearranged upon the face `of the disc 113, and a shutter 117 is ivotallymounted at its end, as at 118, pre erably concentrically ofthe saiddisc. In one position of its pivotal movement, the shutter is designedto rest at one lateral edge against the stop pin 115 and in. suchposition will cover the opening 114. In the operation of the apparatus,the shutter 117 will be maintained in this position, through centrifugalforce, vuntil the disc l113 has been rotated to substantially theposition where the opening 114 will be directly opposite the opening inthe member t 111, corresponding to they opening 9, at which time theparts will be in such position thatl the centrifugal force will act toswing the shutter blade 117 into engagement with the stop pin 116-and atthis time the opening 114 will be uncovered. This movement of theshutter blade is practically instantaneous and, therefore, theadvertising matter to be displayed Will be brought suddenly intoview-with a more or less startling effect.

In the previously described forms of the invention, purely mechanicalmeans are employed for imparting rotary motion to the color impartingmedium but in Figs. 8 and 9 there is. illustrated' a means whereby thismotion may be obtained without the use of gearing or other `positivedriving means. In

.this modification, the ldisplay medium which l corresponds to the.medium 7 is indicatedin general by' the numeral 119 andthe colorlmpartlng medlum` is indicated in general 'Fan blades 125 are fixed uponthe sha bythe numeral 120 and comprises, as before, a disc rovided witha suitable selection of color elds and with an opening121, correspondingto the opening 23, and designed to be brought opposite an opening 122 inthe display medium 119. The disc comprising the medium 120 is fixed uponthe forward a end 'of' a shaft 123 rotatably journaled through the faceplate of the medium 119 andthe substantially cylindrical casin 124.

gt 123 within the casing 124, and the casingis provided in that side ofits circumferential wall which is resented inthe direction of-rotationof tiie member 119 `with an air inlet opening 126, thearea of which maybe regulated by means of a circumferentially adjustable slide 1274arranged and supported vupon the outer side of the said circumferentialwall of the casing. One vor more vent or air outlet perforations 128'maybe formed in an approximately opposite portion of the circumerentialwallfor 'the escape of air from the casing. In'this form of theinvention, as the member 119 israpidly rotated, an inrushing 'current ofair through the opening 126 will act upon the fan blades 125,

thus imparting rotary motion tothe disc Under some conditions, it may befound desirable instead of displaying the surface of the apparatus todirect view of an observer toproject an image of the surface upon ascreen or the like, /and under these conditions an apparatus, such asillustrated in general in Fig. 10 of the drawings, may

lbe employed.- This apparatus comprises a casing 129 housing, forexample, the apparatus disclosed in' Figs. 1 to 4 inclusive, or anyother of the described modifications thereof, and this casing isprovided with a projecting front portion`130 terminating in a lenslmount 131 supporting a projecting 'lens 132, one or more electric lightbulbs,
